If You Own A Telescope, It's Your Duty To Share T-Shirt | Umbravoid
There's an old truth in amateur astronomy: a telescope is meant to be shared. Set one up on a sidewalk and watch strangers gasp at Saturn's rings or the Moon's craters for the first time — that's outreach, and it makes new stargazers on the spot. 'If You Own a Telescope, It's Your Duty to Share' wears that generosity. For sidewalk astronomers and club volunteers who give the universe away one eyepiece at a time. A premium tee for the outreach-minded observer. Available in 7 sizes (S–4XL) and 10 colorways.
